NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed January 9, 1908. Serial No. 409,925.

T 0 all whom it may concern:

Be it known that I, VALENTINE SAND- BERG, a citizen of the UnitedStates, and a resident of the city of New York, borough of Brooklyn, inthe county of Kings and State of New York, have invented a new andImproved Non-Refillable Bottle, of which the following is a full, clear,and exact description.

This invention relates to that class of bottles in which certainobstructions are located in the neck to prevent the same from beingrefilled, but permitting the contents thereof flow of the liquid willnot be impeded.

to freely flow out when the bottle is uncorked and inverted.

The invention has in view a bottle of this nature of comparativelysimple construc tion, which may not be refilled by any of the methodsordinarily resorted to, such for example as by infiltration, suction,etc. To this end 1 preferably construct the neck of the bottle with ashoulder and an annular groove, the groove being located above theshoulder and connecting with passages arranged at substantiallydiametrical points and extending in the direction of the'mouth of thebottle. On the shoulder of the neck is seated a tubular body having aspring pressed valve, and provided thereabove with openings at the sidesdischarging through said groove and passages, the latter extendingslightly above the body, whereby the The spring which forces the valveto its seat is of such stiffness as to readily open under the weight ofa small quantity of liquid when the bottle is inverted, but willimmediately close when the bottle is exhausted.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a central vertical section through the neck of a bottleembodying my invention; Fig. 2 is a like sectional view showing the flowof the liquid when the bot tle is inverted; Fig. 3 is a cross-sectionsub stantially on the line 3-3 of Fig. 1 and Fig. 4 is a perspectiveview of the tubular body which is located in the neck of the bottle.

The body of the bottle may be of any desired form of construction theneck, however, is expanded at its lower portion to provide a shoulder 5,an annular groove 6, ar-

ranged above the shoulder, and at diametrically opposite points in alongitudinal direction, as best shown in Fig. 3, to provide passages 7,connecting with the groove 6 and discharging a substantial distancethereabove.

Located in the neck of the bottle is a tubular body 8, which is made intwo sections fitted together, with one or more tongues 9 formed on onesection and projecting into the other, holding them against relativerotation. The upper section of the tubular body is closed at its upperend and provided with openings 10, for the discharge of such liquid aspasses above the valve, and the lower sec tion is constructed with avalve seat 11, and has openings 12 arranged at opposite sides above saidseat and communicating with the annular groove 6. The lower section ofthe tubular body is also provided with an external flange 14 whichprovides an abutment for a suitable cork or gasket 15, forming aliquid-tight connection with the lower portion of the tubular body and.the bottles neck. The valve seat in the tubular body, as best observedin Fig. 1, has an upwardlyprojecting annular lip 16, which closely fitswithin a hollow valve 17, when the latter is seated, the valve beingnormally forced to its seat by a spring 18, which is interposedtherebetween and the top of the tubular body; the said spring being heldagainst displacement by reducing the top of the valve sulficiently thatthe same may project therein. The diameter of the enlarged portion ofthe valve 17 is such that it neatly fits the bore of the tubular body,and in order that the liquid. may fiow past the same to the openings 10,the said bore is constructed with a number of longitudinal grooves 19.18, which in practice is a hair spring, is of such stiffness as to holdthe valve normally to its seat, but will admit of its opening under theweight of a small quantity of liquid in the bottle when the latter isinverted, and accordingly does not substantially impede the flow of theliquid but prevents the bottle being refilled by infiltration.

The tubular body when placed within the neck of the bottle has the topthereof arranged slightly below the top of the passages 7, and issecured within the neck in any suitable manner. I have shown for thispurpose a split-ring 20 which is arranged in a circum- The springferential groove of the body and projects in a corresponding grooveformed in the neck. The top of the tubular body is provided with afiange 21, which neatly fits within the neck of the bottle and preventsthe insertion of wires or other devices between them, and as theopenings 12 are arranged at substantially right-angles to the passages9, it will be impossible to reach the valve 17 by passing such a devicedown through the passages 7.

It is, however, not essential that the openings 12 be arranged atright-angles to the passages 7, it is only necessary that they be out ofvertical alinement. The neck of the bot tle extends a suitable distanceabove the tubular body for the reception of a cork or other form ofstopper.

While I have shown and described the preferred construction of myinvention, I nevertheless regard the precise embodiment as not material,and consider that I am entitled to such changes as fall within the scopeof the claims annexed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. The combination of a bottle having a neck provided with acircumferential groove, a tubular body located in the neck and having anopening communicating with the groove, said neck also having aconnecting passage discharging above the body, and a valve in the bodycontrolling the communication between the interior of thebottle and theopening in the side of the body.

2. The combination of a bottle having a shoulder in the neck thereof anda circumferential groove in said neck above the shoulder, a tubular bodyhaving a liquid-tight joint with said shoulder and provided withopenings in the side thereof registering with said groove, said neckalso having longitudinal passages connecting with said groove, out ofalinement with said openings and discharging abovethe body, and a valvewithin the body for controlling the passage of the liquid from thebottle through said openings.

3. The combination of a bottle, a body located in the neck of the bottlehaving a liquid-tight joint therewith at its lower end and provided withan approximately central bore, said body being further provided with adischarge opening in the side connecting with the bore, the said neckhaving a discharge passage leading from the opening to a point above thetubular body, and a valve in the body controlling the communicationbetween the interior of the bottle and the open- 1n 2 a. The combinationof a bottle having a shoulder in the neck thereof, a body having aliquid-tight joint around said shoulder and provided with anapproximately central bore, said body being further provided with adischarge opening in the side connecting with the bore, the neck of thebottle being exp anded to provide a' passage leading from the opening toa point above the body, and a valve for controlling the communicationbetween the interior of the bottle and said opening.

5. The combination of a bottle, a tubular body located within andsubstantially fitting the neck of the bottle and having an opening inits side, the neck of the bottle being expanded to provide a passageleading from said opening above the body, a valve within the bodycontrolling the communication between the interior of the bottle and theopening, and a spring arranged above said opening and interposed betweenthe top of the body and the valve, normally forcing the valve to itsseat.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

VALENTINE SANDBERG.
